Important information
GLEEVEC is available only by prescription.
Indication
GLEEVEC® (imatinib mesylate) tablets are indicated for:
- Newly diagnosed adult patients with Philadelphia chromosome– positive chronic myeloid leukemia (Ph+ CML) in the chronic phase (CP)
- Patients with Ph+ CML in blast crisis (BC), accelerated phase (AP), or in CP after failure of interferon-alpha therapy
Who should NOT take GLEEVEC
- Women who are or could be pregnant should not take GLEEVEC. Fetal harm can occur when administered to pregnant women; therefore, women should not become pregnant, as well as be advised of the potential risk to the unborn child if GLEEVEC is used during pregnancy.
- Women who are breast-feeding should not take GLEEVEC because of the potential for serious adverse reactions in nursing infants.
- Sexually active females should use adequate birth control while taking GLEEVEC.
Be sure to talk to your doctor and/or nurse about these issues before taking GLEEVEC.
Warnings and precautions
- Edema (swelling) and severe fluid retention have occurred. Your doctor will weigh you regularly and manage unexpected weight gain by drug interruption and diuretics.
- Cytopenias (reduction or lack of certain cell elements in blood circulation), such as anemia, have occurred. Your doctor will perform complete blood counts weekly for the first month, every other week for the second month, and periodically thereafter. In most cases, your doctor will reduce or interrupt your therapy with GLEEVEC; in rare cases, your doctor may discontinue treatment.
- Severe congestive heart failure and left ventricle dysfunction have been reported, particularly in patients with other health issues and risk factors. Patients with heart disease or risk factors will be monitored and treated for the condition.
- Hepatotoxicity (severe liver problems) may occur. Your doctor will check your liver function before beginning treatment and continue to monitor liver function as needed.
- Bleeding may occur. Severe gastrointestinal (GI) bleeding has been reported in patients with newly diagnosed Ph+ CML.
- GI perforation (small holes or tears in the walls of the stomach or intestine), in some cases fatal, has been reported.
- In patients with certain conditions associated with high eosinophil levels (eg, HES, MDS/MPD and ASM), beginning GLEEVEC has been associated with cardiogenic shock/ left ventricle dysfunction.
- Skin reactions, such as fluid-filled blisters, have been reported with the use of GLEEVEC.
- Clinical cases of hypothyroidism have been reported in patients taking levothyroxine replacement during treatment with GLEEVEC. Your doctor should closely monitor your TSH levels.
- Long-term use may result in potential liver, kidney, and/or heart toxicities; immune system suppression may also result from long- term use.
- GLEEVEC can cause fetal harm when administered to a pregnant woman. Women should be aware of the potential harm to the fetus.
Important safety information
The following serious side effects have been reported in patients taking GLEEVEC:
- Severe fluid retention, which can cause swelling around the eyes or swelling of the lower legs, lungs, and heart; fatal in rare cases
- Low levels of certain blood cells Heart failure/cardiogenic shock Liver problems Skin blistering
- Hemorrhage (abnormal bleeding)
- Low levels of thyroid hormone
Your doctor will check you closely for any side effects to stop more serious complications from occurring. Patients with heart disease or risk factors for heart failure should also be monitored carefully.
GLEEVEC is sometimes associated with stomach or intestinal irritation. GLEEVEC should be taken with food and a large glass of water to minimize this problem. There have been rare reports, including deaths, of stomach or intestinal perforation.
Common side effects of GLEEVEC

Important Information about TASIGNA
TASIGNA (nilotinib) 200-mg capsules are indicated for the treatment of chronic phase and accelerated phase Philadelphia chromosome–positive (Ph+) chronic myelogenous leukemia (CML) in adult patients resistant or intolerant to prior therapy that included imatinib. The effectiveness of TASIGNA is based on hematologic and cytogenetic response rates. There are no controlled trials demonstrating a clinical benefit, such as improvement in disease-related symptoms or increased survival.
WARNING:
QT PROLONGATION AND SUDDEN DEATHS
TASIGNA prolongs the QT interval. Sudden deaths have been reported in patients receiving nilotinib. TASIGNA should not be used in patients with hypokalemia, hypomagnesemia, or long QT syndrome. Hypokalemia or hypomagnesemia must be corrected prior to TASIGNA administration and should be periodically monitored. Drugs known to prolong the QT interval and strong CYP3A4 inhibitors should be avoided. Patients should avoid food 2 hours before and 1 hour after taking dose. Use with caution in patients with hepatic impairment. ECGs should be obtained to monitor the QTc at baseline, seven days after initiation, and periodically thereafter, as well as following any dose adjustments.
Contraindications
You should not use TASIGNA if you have one of the following:
- Hypokalemia
- Hypomagnesemia
- Long QT syndrome
What is the most important information to know about TASIGNA?
TASIGNA can cause a possible life-threatening heart problem called QT prolongation. QT prolongation causes an irregular heartbeat, which may lead to sudden death.
Your doctor should check your heart with a test called an "ECG:"
- Before taking TASIGNA
- Regularly during treatment
- 7 days after starting TASIGNA
- After any dose changes
You may lower your chances for having QT prolongation with TASIGNA if you:
- Take TASIGNA on an empty stomach. DO NOT TAKE TASIGNA WITH FOOD
Take TASIGNA:
- At least 2 hours after eating any food, and
- After taking TASIGNA, wait at least 1 hour before eating any food
- Avoid grapefruit, grapefruit juice, and any supplement containing grapefruit extract while taking TASIGNA. Food and grapefruit products increase blood levels of TASIGNA in your body
- Avoid taking other medicines, vitamins, or herbal supplements with TASIGNA that can also cause QT prolongation
TASIGNA is a prescription medication.
TASIGNA comes in 200 mg capsules. Your doctor will prescribe 400 mg of TASIGNA to be taken twice a day for a total daily dose of 800 mg. Each dose should be taken approximately 12 hours apart.
Swallow TASIGNA capsules whole with water.
- Do not open TASIGNA capsules.
- Do not drink grapefruit juice, eat grapefruit, or take supplements containing grapefruit extract. It may affect the levels of TASIGNA in the blood.
- If you miss a dose, take your next dose as scheduled. Do not take a double dose to make up for a missed dose.
Before taking TASIGNA
Talk to your doctor or pharmacist about all other medication(s) you may be taking, including prescription medicines, over-the-counter medicines, vitamins, and herbal supplements, since they may affect how TASIGNA works and increase your chance of serious and life-threatening side effects.
Before taking TASIGNA, tell your doctor if:
- You have a heart disorder or are taking medication for the heart
- You have an irregular heartbeat
- You have QT prolongation or a family history of it
- You know that you suffer from low blood levels of electrolytes, such as potassium or magnesium; or you have a liver or pancreas disorder
- Also tell your doctor if you are pregnant, breast feeding, or lactose-intolerant
Call your doctor right away if you faint or have an irregular heartbeat while taking TASIGNA.
These can be symptoms of QT prolongation.
Call your doctor immediately if you experience any of these symptoms.
Serious side effects
TASIGNA is sometimes associated with serious side effects, with symptoms that include:
- Irregularity in heartbeat or fainting
- Yellow skin and eyes
- Unexplained bleeding or bruising
- Shortness of breath
- Blood in urine or stool
- Swelling of hands, ankles, feet, or face
- Unexplained weakness
- Sudden stomach area pain with nausea and vomiting
Common side effects
Most patients experience side effects at some time. Some common side effects you may experience include:
Low blood count Rash Nausea and vomiting Headache Itching Tiredness
Diarrhea
Constipation
Be sure to tell your doctor or pharmacist if you have any side effects during treatment with TASIGNA.
Women taking TASIGNA should avoid becoming pregnant.
- Tell your doctor if you are pregnant or planning to become pregnant. TASIGNA can harm a fetus (unborn baby).
- Women who can get pregnant must use effective birth control during treatment with TASIGNA.
Women should not breast-feed while taking TASIGNA.
- Tell your doctor if you are breast-feeding.
If you take too much TASIGNA, call your doctor or poison control center right away.
Your doctor will check your heart, do regular blood tests and take bone marrow samples during treatment with TASIGNA. These are done to check for side effects with TASIGNA and to see how well TASIGNA is working for you. Your doctor should check your blood to monitor the amount of blood cells (white blood cells, red blood cells, and platelets) during treatment. These should be checked every two weeks for the first two months and then monthly thereafter, or as considered necessary by your doctor. Your doctor may have you stop TASIGNA for some time or reduce your dose if you have side effects with it.
